Guys HI . Sure this has been asked before but cant find it

Easy description

Car has new head, injectors done, new tps ,plugs, leads ,new fuel pump and filter (all last week )

When car is cold and u take off it holds back (feels dead)when throttle is held at 1/4 to 3rd pedal at approx 2500 (feels like lack of fuel)

engine idles great

when u push pedal too 1/2 it powers away okay

Now it does the surge all gears and gets slightly better when hot but still can feel it

ne ideas Mike

Have you tried reading the diagnostic codes from the ECU? This would be a great starting point.
